The STU paddle dilema……..

I know the paddle tire question has been beat to death, but I have to ask one more. I have made the decision on buying STU Blasters, 28" for my 1000 with a turbo running 10 plus lbs of boost. The question is which paddle, #1 or #2? I’ve ran #1’s on a couple of sets I’ve had on heavy quads, and loved them but I’ve been told I need the #2 paddle for the RZR. Has anyone ran both on a RZR and have an opinion? Thanks, Dan
